Toshiba VFAS3-4015PC-F frequency converter

Toshiba VFAS3-4015PC-F frequency converterVF-AS3 can provide different functions specifically designed for various applications.

VF-AS3 is an ideal choice to meet various application needs.

Applications in the oil and gas/mining industry

Hydraulic pump/compressor/conveyor/crusher

Multi level rated power - motor control performance

VF-AS3 has multi-level rated power and can be used to drive different applications with overload characteristics of overload (150% -60 seconds overload capacity) and normal load (120% -60 seconds overload capacity). This frequency converter is suitable for both heavy-duty and light-duty applications.

When the output frequency is greater than or equal to 0.3 Hz, the starting torque of sensorless vector control can reach 200%. VF-AS3 can achieve high starting torque and high-precision regenerative torque under low frequency conditions.

Easy setup through automatic tuning function

VF-AS3 has automatic tuning function, which can automatically optimize various parameters of the frequency converter.

Through the automatic tuning function, the frequency converter can also easily set the inertia moment of mechanical equipment.

Permanent magnet motor drive

VF-AS3 adopts permanent magnet motor drive technology as a standard feature of the frequency converter. VF-AS3 can be used to control induction motors and permanent magnet synchronous motors with and without feedback sensors to ensure that the motors meet the needs of various applications.

VF-AS3 can be used to drive both embedded permanent magnet motors (IPM) and surface permanent magnet motors (SPM).

Applications in the Conveyor/Crane Industry

Transporter/Conveyor/Crusher/Compressor

Embedded positioning control

VF-AS3 has point-to-point, pulse input, and directional sensor/sensorless position control functions, suitable for applications such as machining machinery that require high-precision control.

Achieve excellent flexibility through 'MyFunction' (logical functionality)

The "MyFunction" has added programming capability for the input/output signals of the frequency converter, which does not require the use of any external relays or programmable logic controllers (PLCs). This feature can effectively reduce the space and cost required by the system.

MvFunction "has a relay sequence function that combines logical operation functions. The relay sequence function allows the frequency converter to automatically run 52 steps (4 steps * 7 units+24 steps) without a programmable logic controller. Due to its ability to directly use internal data and signals, this feature has a faster processing speed than control devices with programmable logic controllers.
